Research on joint control during arm movements in adults has led to the development of the Leading Joint Hypothesis (LJH), which states that the central nervous system takes advantage of interaction torque (IT) and muscle torque (MT) to produce movements with maximum efficiency in the multi-jointed limbs of the human body. A gap in knowledge exists in determining how this mature pattern of joint control develops in children. Prior research focused on the kinematics of joint control for children below the age of three; however, not much is known about interjoint coordination with respect to MT and IT in school-aged children. In the present study, joint control at the shoulder, elbow, and wrist during drawing of five shapes was investigated. A random sample of nine typically developing children ages 6 to 12 served as subjects. The task was to trace with the index finger a template placed on a horizontal table. The template consisted of a circle, horizontal, vertical, right-diagonal, and left-diagonal line. Analysis of muscle torque contribution (MTC) revealed the individual roles of MT and IT in the shoulder, elbow, and wrist joints. During drawing of the horizontal line, which requires the most difficult joint control pattern in adults because it does not allow the use of IT for joint rotation, joint control was found to change through development. For the youngest children, the function of elbow MT modified to suppress IT, thereby producing large elbow rotation. The oldest children simplified this by using the shoulder as the principal joint of movement production and with decreased assistance from the elbow. For the other four drawing movements, differences in the pattern of joint control used by all of the subjects was unaffected by an increase in age. Overall, the results suggest that in children above 6 years of age, minor changes in joint control occur during drawing of relatively simple movements. The limited effect of age that was observed could be related to the restriction of movements to the horizontal plane. For a future study, three-dimensional movements that provide more freedom in joint control due to redundancy of degrees of freedom could be more informative about developmental changes in joint coordination.

How do children understand how others see the world? I examined correlations between 4-8 year old children's understanding of beliefs and their understanding of other ways that people represent the world. Beliefs that I measured are understanding of pretense, understanding that things can have multiple identities, understanding that people can know things by inference, and understanding that people can look at the same thing and have different representations of it. I predicted that there would be correlations among these tasks. In particular, I predicted children would be able to understand these tasks when they understood true and false beliefs, based on current theories on belief understanding. I predicted that the classic false belief task alone would not be a good predictor of task performance, but that the combination of true and false belief tasks would. Participants were 100 children recruited at the Phoenix Children's Museum between ages 4 and 8. Previous research has found that children pass all of these tasks between the ages of 6 and 8, but no other studies have looked at the inter-correlations among them. Contrary to my prediction, children did not pass these tasks all at once, but scores went up gradually with age and belief understanding.

This honors thesis is a combination of analytical and creative endeavors. The research portion of the project examines contemporary transgender issues, including social, emotional, and cultural concerns. Most notably, the research focuses on the relationship between social support and mental health. These findings suggest that children who fail to receive adequate support are liable to face severe developmental and emotional consequences. The accumulation of this research ultimately serves as the foundation and justification for the creative work, which is presented as a children's book directed at transgender and gender non-confirming youths.

Children's wellbeing has been of utmost concern to society, and recently this topic has taken a particular focus in both health and achievement. As the focus shifts towards promoting a healthier and more academically successful youth, the relationship between the two warrants investigation. Specifically, the relationship between physical fitness and academic performance (i.e. grades) in 4th grade students was assessed. A cross-sectional design was used to assess physical fitness of children (M=9.39 years) by means of the FITNESSGRAM assessment tool. Third-quarter grades were used to measure academic performance. Relationships between the variables were determined through bivariate plots, Pearson product moment correlation analysis, independent t-tests, and a three-step regression analysis. The results show a significant relationship between students' aerobic fitness and academic performance. Furthermore, the findings of this study suggest incremental validity between aerobic fitness and academic performance, thus implying predictive value associated with increased physical fitness and academic achievement.

This creative project is a children's book entitled Sheldon the Shy Tortoise. Accompanying the story is a literature review of the research on childhood shyness. The purpose of the project is to gain a better of understanding of shyness in childhood. Topics covered in the literature review include risk factors and causes, negative social and behavioral effects, impact on academics, and treatment options. Using this information, the children's book was written. It aims to be fun for children to read while also providing insight and encouragement into some of the problems related to being shy. The story features animal characters and a relatively simple plot so it is easily understandable by the target audience of late-preschool and early-elementary children. The main character, Sheldon the tortoise, is often physically and metaphorically "stuck in his shell". He wants to participate in social activities but is afraid to do so. Through a series of events and interactions, Sheldon starts to come out of his shell in every sense of the phrase. The book is illustrated using photographs of hand-crocheted stuffed animals representing each of the characters. By incorporating scholarly research into the writing process, children will hopefully be able to gain an understanding of their shyness and ways to help decrease it. Teachers should be able to better understand their shy students and understand some of the unique challenges of working with shy children. This creative project helps convey necessary information to children and families during a critical period of development.

It is well known that the lack of care coordination in the healthcare system causes numerous problems including cost inefficiency and inconsistent care, specifically for complex pediatric and adult patients. Many pediatric patients have complex medical and social service needs which can be expensive for both the patient’s parents and the general healthcare system. Therefore, it is difficult for the healthcare system to deliver the highest quality care possible, due to the number of appointments that have to be scheduled (with some being out of state), the large volume of physical health records, and overall lack of time parents have to coordinate this care while also caring for themselves and other family members. It is integral to find a more efficient way to coordinate care for these patients, in order to improve overall care, cost efficiency, and outcomes. <br/>A number of stakeholders in Arizona came together to work on this problem over several years. They were funded through a PCORI Eugene Washington Engagement grant to investigators at ASU. This project, Take Action for Arizona's Children through Care Coordination: A Bridge to Action was developed in order to further develop a research agenda and build the network (PCOR). Regional conferences were conducted in Flagstaff, Yuma, Phoenix, and Tucson, as well as a final capstone conference held in Phoenix. At these conferences, frustrations, suggestions, and opinions regarding Children with Special Health Care Needs (CSHCN) and navigating the healthcare system were shared and testimonials were transcribed.<br/>This study focused on the capstone conference. The study design was a strategic design workshop; results of the design analysis were analyzed qualitatively using descriptive content analysis. Themes described parent’s common experiences navigating the system, impacts resulting from such experiences, and desires for the care coordination system. Quotes were then grouped into major themes and subthemes for the capstone conference. After these themes were determined, the overarching goals of stakeholders could be assessed, and implementation projects could be described.

Brave Bears was a Barrett creative project that operated under local non-profit organizations, Amanda Hope Rainbow Angels and Arizona Women’s Recovery Center. Amanda Hope Rainbow Angels provides support and education for children fighting cancer and their families. Arizona Women’s Recovery Center provides rehabilitation programs for women fighting substance abuse and housing for the women and their children. The Brave Bears Project was focused on helping children in these situations cope with the trauma they are experiencing. The children received a teddy bear, which is a transitional object. In addition, a clay pendant with the word, “brave” pressed into it was tied around the bear’s neck with a ribbon. A poem of explanation and encouragement was also included.<br/><br/>The teddy bear provided comfort to children experiencing emotionally distressing situations as they receive treatment for their illness or as their mom undergoes rehabilitation. This can be in the form of holding the teddy bear when they feel frightened, anxious, lonely or depressed. The “brave” pendant and poem seek to encourage them and acknowledge their trauma and ability to persevere.

The purpose of this study was to examine the validity of a modified Assisted Cycling Therapy bicycle for improving depression in children with Down Syndrome (DS). Seven participants completed 2x/week for 8 weeks, 30 minutes at a time of ACT, in which participants’ voluntary pedaling rates were augmented via the bicycle motor, ensuring that they were pedaling at a rate greater than their self-paced rate. Depression was measured using a modified version of the Children’s Depressive Inventory, called the CDI-2. Our study demonstrated that the scores from the CDI-2 decreased, demonstrating less depressive symptomatology after the conclusion of the 8 week intervention. Our results were interpreted via our model of the mechanisms involved in influencing the success of ACT. Future research would include a greater sample size, a more relevant measure of depressive scores, and a consistent data collection environment. However our initial pilot study showed promising results for improving mental health in children with DS.
